We're dividing 53714921 by 171 
We want to figure out the number of times 53714921 can be divided by 171.

Going ahead to step 1:
When dividing 5 by 171, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 171

Advancing to step 2:
171 can be fit into 53 0 times, resulting in a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Include the next digit (7) from the dividend after 53, then repeat: 537 / 171

On to step 3:
171 goes into 537 3 times with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 513 from 537 and we're left with 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 171

On to step 4:
The number 171 fits into 241 1 times, leaving a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we subtract 171 from 241, we get 70.
Grab the next digit (4) from the dividend, add it to 70, then carry on: 704 / 171

On to step 5:
704 divided by 171 is 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 314.0
If we take 684 away from 704, we end up with 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 171

Step 6:
171 can be fit into 209 1 times, resulting in a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 3141.0
The remainder is 38 after subtracting 171 from 209.
Grab the next digit (2) from the dividend, add it to 38, then carry on: 382 / 171

Let's proceed to step 7:
171 can be fit into 382 2 times, resulting in a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 31412.0
Subtract 342 from 382 to get 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 171

Step 8:
When dividing 401 by 171, we get 2 with a remainder of 59.
Record the quotient 2 as the next digit in the result. 
Result so far: 314122.0
Subtracting 342 from 401 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 9:
If we divide 590 by 171, we get 3 and a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 314122.3
If we take 513 away from 590, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 10:
171 can be fit into 770 4 times, resulting in a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 314122.34
If we take 684 away from 770, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 11:
If we divide 860 by 171, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 314122.345
If we subtract 855 from 860, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
If we divide 50 by 171, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 314122.345
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
The number 171 fits into 500 2 times, leaving a remainder of 158.
Record the quotient 2 as the next digit in the result. 
Result so far: 314122.34502
If we subtract 342 from 500, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 14:
If we divide 1580 by 171, we get 9 and a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 314122.345029
Deduct 1539 from 1580 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 15:
171 goes into 410 2 times with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 314122.3450292
The remainder is 68 after subtracting 342 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 16:
171 can be fit into 680 3 times, resulting in a remainder of 167.
Put 3 as the next digit of the answer. 
Result so far: 314122.34502923
Subtract 513 from 680 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

The final outcome is 314122.34502923, with a leftover of 1.67e-07.
